GAS-COCK.

SPECIFICATION formingpart of Letters Patent No. 654,559, dated July 24, 1900.

Application filed October 16, 1899. Serial No. 733,804. (No model.)

To all whom, it may concern,.-

Be it known that I, ANDREW J'. WIEGAND, residing at Baltimore, in the State of Maryland, have made certain new and useful Irnprovements in Gas-Cocks, ot' which the following is a specification.

My invention is an improvement in gascocks, and particularly in that class of such devices known as self-lighting gas-cocks and in which the gas is ignited by the impin ging of such gas upon an igniting suhstance such, for instance, as platinum sponge.

The invention consists in certain novel constructions and combinations of parts, as will be hereinafterdescribed, and pointed out in the claims.

In the drawings, Figure l is a sectional elevation of my gas-cock on about line l l of Fig. 2. Fig. 2 is a longitudinal section on about line 2 2 of Fig. l. Fig. 3 is a detail viewcf the spherical valve and its handle. Fig. 4: shows a modification in the manner of supporting the holder for the igniting substance. Fig. 5 is a detail view of such holder. Fig. 6 is a longitudinal section of a burner, showing a somewhat-different construction for effecting the connecting engagement between the burner-section and the casingsleeve from that shown in Fig. l; and Fig. 7 illustrates the application of the invention to a burner having a mantle of the type illustrated in said figure.

In the construction shown in Figs. l and 2 the burner is composed of the burner-section A, the base-section B, the casing-sleeve C, the valve D, and the holder E for the igniting substance.

The burner-section A has a tip A at its upper end, which may be of any desired construction, is provided at its lower end with the lateral flange A2, and has in said lower end the seat A for the valve D, and the main port A4 and the igniting-port A5 lead from the seat A3, as shown. The port A4 leads to the tip A and the port A5 leads, preferably, to a short tube AG, having a discharge at A7 below the igniting substance and in such position that the gas will attack the extreme end of the igniting substance F, which is carried by the holder E. The igniting substance F may be platinum sponge or any allied sub= stance which will become incandescent and produce a flame when impinged by illuminating-gas in the presence of air.

The holder E is provided with a tubular portion E to embrace its support, which may be the section A, as shown in Fig. l, or a separate supporting-standard G, carried by the nozzle A, as shown in Fig. 4E. The holder E also has the tube-like guard portion E2, which partially incloses the iguiting substance, operates to protect the same, and is of gauze or other foraminated material to permit the ready passage of air to the igniting substance.

As shown in Fig. 5, the igniting substance F is held in the partition between the portions El and E2,'and this is preferably effected by forming such partition with an opening to receive the igniting substance F, which is preferablytapered slightly in order to hold it in place, as will be understood from Figs. l and 5.

The base-section B is threaded externally at its upper end and is provided in such upper end with a seat B for the valve D and has at such end a port B2, which registers with the port in the valve, as presently de scribed.

The casing-sleeve C is litted over the section A, has internally near its upper end the shoulder O to lit upon the fla-nge A2 of the section A, has its lower end threaded internally te screw upon the base-section B, and is provided with a slot or opening O2 for the passage ef the handle D of the valve D. As will be understood from what follows, the upper and lower walls of the opening C2 operate to limit the movement of the valve in both directions, and thus effect the proper registration of the port D2 of the said valve with eitherthe main port A4 or the ignitingport A5 of the main section A, as will be read ily'understood from Fig. l of the drawings.

B v the described construction of the burnere` section A, base-section B, and sleeve O it is evident that the sleeve O is engaged with the section A and is threaded on the section B, so the sections A and B may be adjusted relatively in order to clamp the valve D by and between the said sections. When I use the construction shown in Figs. l and 2 for effecting the engagement of the sleeve C with.

IOO

the section A, I find it desirable to employa screw H by which to lock the section A from turning in the sleeve C, and so maintain the parts A and C in the desired relation. In this construction the lower section B may be locked by a screw, as shown, and the upper section may be locked by screwing it down so hard as to causeits shoulder to lock against the upper end of the casing-sleeve. It may be desirable, however, in some instances to employ the construction shown in Fig. 6, in which I represent the sleeve as threaded at I and I', respectively, to the base and burner sections. Manitestlyin this construction, as in that shown in Fig. I, the sleeve is engaged with the burner-section and is threaded into connection with the base-section, and this construction does not involve any departure from the spirit of my invention.

The valve D is spherical in form, so itwill readily fit the seats of the main and base sections and will always iind its seat Without any trouble. This spherical construction also enables the assembling of the parts, as shown, one or both of the sections A and B turning into connection or into position to receive the valve. The valve D has a port D2 in constant register with the port B2 of the section B and contracted at its upper end at D3, so such end may be moved by depressing the handle D out of register with the main port A4 and into register With the igniting-port A5 and back again after the igniting operation is effected. The port D2 when moved at D3 into register with either of the ports A4 and A5 moves out of register with the other one ot' such ports, sogas is never supplied at the same time through both of the said ports. In other words, when the gas is feeding through igniting-port A5 the port A4 is closed, and Vice versa.

The handle Dl is usually held in the position shown in Fig. l by the spring D, which, as shown, is a plate-spring secured at one end to the handle D and bearing at its free end against the base-section B, so it will operate when the handle D is moved to the dotted position, Fig. l, and released to instantly return said handle to its normal position, (shown in full lines, Fig. 1,) in which position the port D2 registers with the main port AA1 of the burner-section A and feeds the gas to the tip A', as will be understood from Fig. l. In the operation of the described construction if the valve be adjusted to the dottedline position, Fig. l, and held momentarily the gas will escape through the port A5, impin ge they ignitin g substance F, and beignited into a llame. Then if the handle Dl be released the valve will be adjusted to the fullline position shown in Fig. l and the gas will feed through the main port A4 and be ignited by the ame from the substance F, which is held adjacent to the tip of .the burner, as shown.

In Fig. 7 I show an extended tube J leading from the igniting-port to a position adjacent to the mantle K, so the invention may be employed for lighting burners of the mantle class. l

I iind it desirable to center the valve D by means of a screw D, projected through the sleeve C and into the said valve, as shown in Fig. 2. This centering-screw may be omitted by fitting the handle D so tightly in the slot C2 as to properly guide the valve; but this tight fitting of the parts may impede the operation of the valve, and I prefer the construction as shown in Fig. 2.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
